Implementations

impl VioSndShmStream

fn new( buffer_size: usize, num_channels: usize, format: SampleFormat, frame_rate: u32, stream_id: u32, direction: StreamDirection, vios_client: Arc<Mutex<VioSClient>>, client_shm: &dyn AudioSharedMemory<Error = Error>, state: Arc<Mutex<StreamState>>, ) -> Result<Box<dyn ShmStream>, BoxError>

Creates a new shm stream.

Trait Implementations

impl BufferSet for VioSndShmStream

fn callback(&mut self, offset: usize, frames: usize) -> Result<(), BoxError>

Called when the client sets a buffer offset and length.

fn ignore(&mut self) -> Result<(), BoxError>

Called when the client ignores a request from the server.

impl Drop for VioSndShmStream

fn drop(&mut self)

Executes the destructor for this type.

impl ShmStream for VioSndShmStream

fn wait_for_next_action_with_timeout( &mut self, timeout: Duration, ) -> Result<Option<ServerRequest<'_>>, BoxError>

Waits until the next time a frame should be sent to the server. The server may release the previous buffer much sooner than it needs the next one, so this function may sleep to wait for the right time.

fn frame_size(&self) -> usize

Get the size of a frame of audio data for this stream.

fn num_channels(&self) -> usize

Get the number of channels of audio data for this stream.

fn frame_rate(&self) -> u32

Get the frame rate of audio data for this stream.
